Yes, you can wear stripes below the waist — when they're on a diagonally patterned, eye-fooling maxi skirt ($29, Lilly White). Top with a breezy crochet sweater ($68, Kensie); its cutouts are like built-in air-conditioning.

If you've avoided white dresses — aren't they just stain magnets that visually add pounds? — try this lace-up-placket sheath ($158, White House Black Market). The contoured fit and stretchiness do the dieting for you. Plus, you can toss it right into the washing machine (see tip below) — so you can enjoy even drippy Popsicles stress-free.

CARE TIP: To keep whites from yellowing, our GHRI pros advise washing after each wearing, even if they look clean, so soil won't build up. Also, a cup of baking soda added to the wash boosts cleaning power.
